This glass of champagne, I see its colour, I hear its sparkle, I inhale its bouquet, I taste its savour, I feel its coolness and formlessness, and I know its quality. In fact I completely cognise it.
What have I cognised? Champagne. But what is that? A concept, champagne-concept. What could that be apart from the cognising of it? Surely it is no thing whatever apart from the cognising of it. What else could there be for it to be? If it were something else, how could I know that it was something else, or what that was? Only by cognising. Have I any other way of knowing anything?
Then what cognised it? An indefinable concept called 'mind' cognised it. What is this indefinable concept? Being a concept, it too is cognising - 'cognising' cognising 'cognising'?
It is THIS which cognises? What else could it be? And if it were something else, how could I ever know that it is something else, or what that is? What else could there be to know that or anything whatever?
So 'mind' is what cognises, and what is cognised is 'mind' And they are 'this' - this which cognises and that which is cognised.
Where do I come in? I must be 'this and that', subject and object! Evidently, inevitably I must be this 'mind' which appears to be the cogniser, and that champagne which appears to be the cognised, the cogniser and the cognised, both and neither, all and no thing.
'I' am Champagne Charlie!
Note: What are you saying? It is wine, made from grapes, dextrose and levulose transformed by ferments into alcohol, acid, carbonic acid gas, etc., etc.? Is it indeed? And how do you know that? Memory? And what is all that? Concepts. Results of cognition, what is termed 'knowledge'. 'Cognising' cognising - 'cognising'.
